Scanning Instructions

There are many options for scanning, but these are the most important (to me at least)

• Scan the entire visible part of the page; I can crop and rotate easily.
• Scan at 300 dpi, greyscale (for B&W pages, otherwise, colour), save as JPEG with quality level ~75 (pages will be about 1Mb)
• Scan with "descreening" turned on (see below)
• I will want to work on individual images, so uploading images to a service like Dropbox is ideal, but a zipfile is also fine. A PDF file is not preferred, but I can work with it; it's just more work for me to extract the images.

I use different scanning settings for different types of pages.

• I try to get the best scans of the grad pages, and I can usually set things up so that I scan all of them without changing any settings, dimensions, ...
• For pages with just text or line drawings, I turn off descreening (because there is no screening to descreen), and can scan pages in half the time. I don't think there is much if any harm in having descreening on all the time.
• For ads, I scan at 150dpi instead of 300, with descreening for ads with photos of people.
• I scan odd-numbered pages upside-down so they can be in the same position on the scanner as the even pages.

Scanning Priorities

Some parts are higher priority than others. Here are my preferences, in descending order

• Cover
• Grad pages (including 'Also Graduating'), Group photo
• Staff / Faculty / Teachers, Last Will & Testament (from class to teachers)
• Memorial pages
• Inside cover (in one or two scans; I can join)
• Prelude editorial, prelude staff, dedications, thanks
• Section Pages (one or two page at the start of each section, including: Staff, Grads, Activities/Clubs, Sports, Creativity/Arts, Undergrads, Advertising)
• Title page (usually page 1), Table of contents, Ending page, Time Capsule
• Activities pages: Student Council, Reach for the Top, G.C.O., Music, Theatre, ...
• Art pages, esp. colour

Scanning Examples: Descreen and Unsharp

Descreening will reduce the interference patterns due to the printing process used in Prelude Yearbooks. Unsharpening is sometimes useful to make a scanned image smoother. The images on this page were all scanned at 300 dpi, saved in JPEG format at 77 quality. They are scaled to the window width, so you can change the width and see the interference patterns, at least until your browser compensates.
